The JIT is not active by default.  A backtrace can help, you can try

  ./libtool --mode=execute gdb --args ./gst <rest of command line above>
  handle SIGSEGV noprint
  run
  bt

Also, can you try the latest git instead of 3.2?  I plan to release 
3.2.1 in a few days.  I honestly don't believe it will improve the 
situation, but just to be sure.
